compare to rasters and set lower value to Nodata

Hi,I need to compare two raster sets with elevation values. I want the lower values to be set to Nodata.With the RasterCalculator tool and the Setnull function. "Setnull([grid1] < [grid2], [grid1])"I managed to acomplish this.I would like to include this in a Model with ModelBuilder. How do I accomplish this with the Set Null tool ?
